We build custom decks in every Canadian province — licensed local crews, fixed-price quotes, one 25-year BestDecks warranty. From first sketch to last board, under one contract.
One contract. One warranty. One crew from the first sketch to the last board — built by Canadians, for Canadian winters.
Composite, cedar, PVC, pressure-treated and ipê — engineered for freeze-thaw, rated by our crews on real Canadian jobs.
Composite decking is an engineered board made from a mix of wood fibres and recycled plastic polymers, topped with a protective polymer cap. The cap shields against UV fading, staining, mould, and moisture — which is why composite decks maintain their appearance for decades without the annual staining ritual that wood decks demand.
Pressure-treated (PT) lumber is softwood — typically Spruce-Pine-Fir (SPF) or Southern Yellow Pine — that has been infused with chemical preservatives under high pressure in a sealed cylinder. The treatment prevents rot, insect damage, and fungal decay that would destroy untreated softwood within a few years of outdoor exposure.
Western Red Cedar (Thuja plicata) is the only major decking wood grown and harvested in Canada. The forests of British Columbia produce the world's supply, making cedar the most authentically Canadian decking choice — with shorter supply chains and lower carbon footprint than imported composite or exotic hardwood.
PVC (polyvinyl chloride) decking and composite decking look similar but differ at the molecular level. Composite contains wood fibres mixed with plastic — typically 50/50. PVC decking is 100% cellular PVC with zero wood content.
Every Canadian province enforces railing requirements based on the National Building Code (NBC). The rules are non-negotiable — a deck without proper railings fails inspection and cannot be used legally.
Backyards, pool surrounds, rooftops, waterfront docks, cottages, multi-level builds — each with its own structural logic.

Structure, fasteners and finish — one contract.
From one Toronto backyard in 2010 to every province today.
BestDecks replaced our 15-year-old pressure-treated deck with a 380 sq ft composite build. The crew showed up when they said they would, the Toronto permit was handled by them, and the final invoice matched the quote to the dollar — $16,200 on a $17,000 budget. One contract, one project manager, zero surprises.
BestDecks holds a valid RBQ licence, which mattered to me in Quebec — I'd had two neighbours burned by unlicensed crews. The Montreal BestDecks team built our 500 sq ft cedar deck, handled the permit with Ville de Montréal, and finished three days ahead of schedule. Every fastener was stainless, every joist was properly flashed.
We only visit our lakefront cottage 6 weekends a year, so we asked the BestDecks Okanagan crew for zero-maintenance. They recommended PVC decking with hidden fasteners and aluminum rails — the whole 650 sq ft build took 9 days. Three seasons in, the deck still looks the day it was finished. That's exactly what we paid for.
Every BestDecks crew is local — they know the permit office, the climate, and the suppliers in your city.
Straight answers on materials, permits, warranties, and what to expect during a build.
A deck in Canada costs $6,000 to $45,000 installed, depending on size, material, and location. For a standard 300 sq ft deck, pressure-treated wood runs $6,000–$12,000, composite runs $9,500–$21,500, and premium materials like PVC or aluminum range from $12,000 to $45,000. Labour costs vary significantly by province — $12–$18/sq ft in Atlantic Canada versus $28–$40/sq ft in Vancouver. Additional costs include permits ($100–$500), railings ($1,500–$7,500), and footings ($300–$3,600 depending on frost line depth and method). BestDecks gives you a fixed-price quote within 24 hours based on your project specs — no endless back-and-forth, no pressure tactics, one number that covers the whole build. The best time to build is late winter through early spring — booking your contractor in February or March avoids peak-season surcharges and ensures your deck is ready for summer entertaining. Off-season builds (October–March) can save 15–25% on labour costs.
Composite decking is worth it for most Canadian homeowners who value low maintenance over the lowest upfront cost. While composite costs 2–3x more than pressure-treated wood to install, it requires zero staining, sealing, or annual treatment — saving $200–$400 per year in maintenance. Over 10 years, the total cost of ownership often favours composite. Composite also handles Canada's 100+ annual freeze-thaw cycles better than wood because the polymer cap prevents moisture absorption that causes wood to crack and splinter. The main drawback is the initial investment — for homeowners on a tight budget or building a very large deck (500+ sq ft), pressure-treated wood may be the more practical choice.
For Canadian cold climates, composite decking with a capped polymer surface is the best all-around choice. The cap prevents moisture absorption, which is the primary cause of freeze-thaw damage in wood decks. Look for brands that publish freeze-thaw cycle testing data — MoistureShield specifically markets its freeze-thaw resistance for Canadian winters. For extreme cold regions (Winnipeg, Edmonton, Thunder Bay) where temperatures reach -40°C, ensure the composite has a proven track record in similar climates. PVC decking is another excellent cold-climate choice since it contains zero wood fibre to absorb moisture. Avoid untreated cedar in extreme cold — while beautiful, it absorbs more moisture than composite and experiences more freeze-thaw damage. For the absolute coldest locations like Saguenay or Thunder Bay, consider aluminum decking — it's completely immune to temperature extremes and will outlast any other material by decades.
In Ontario, you typically need a building permit if your deck is more than 24 inches (600mm) above grade or exceeds 100 sq ft when attached to the house. Freestanding ground-level decks under 100 sq ft generally don't require permits, but rules vary by municipality — always check with your local building department. Permit fees range from $200 to $500 depending on the municipality. The permit process typically takes 2–6 weeks and includes at least two inspections: one for footings (before pouring concrete) and one for the completed structure. Building without a required permit can result in fines, forced removal, and complications when selling your home — the cost of the permit is always worth it.
A pressure-treated wood deck in Canada lasts 15–20 years with proper maintenance and only 5–8 years without maintenance. The key factor is regular staining and sealing — PT wood must be stained every 1–2 years to protect against UV damage, moisture absorption, and the freeze-thaw cycles that crack and splinter unprotected wood. The structural components (joists, beams, posts) typically last longer than the deck surface — 20–25 years if properly treated and ventilated. If your PT deck boards are deteriorating but the substructure is sound, you can replace just the surface with composite at 40–60% of the cost of a full rebuild.
